Features, pricing, ratings, and pros & cons — compared head-to-head.
Array ASI SSL Intercept is a commercial next-gen firewalls tool by Array Networks. Safing Portmaster is a free next-gen firewalls tool by Safing. Compare features, ratings, integrations, and community reviews side by side to find the best next-gen firewalls fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market security teams with hybrid cloud deployments need Array ASI SSL Intercept to inspect encrypted traffic without becoming a bottleneck; its hardware-accelerated processing hits 120 Gbps while supporting physical, virtual, and cloud appliances in the same policy framework. The tool handles both inbound and outbound decryption with Layer-2 and Layer-3 flexibility, letting you avoid the "decrypt everywhere or nowhere" trap that locks teams into single-vendor stacks. Skip this if you're looking for integrated threat response; ASI decrypts and classifies traffic for downstream tools, so you still need your own IDS, firewall, and analytics layer to actually stop threats.
Startups and individual security practitioners who need granular per-application network control without licensing friction should use Safing Portmaster; it's free, open-source, and runs locally so you own the ruleset and logs. The tool covers NIST DE.CM continuous monitoring of network anomalies and PR.IR infrastructure resilience through application-level firewall rules, kill switch, and encrypted DNS, giving you visibility most OS firewalls skip. Skip this if your team expects vendor support, cloud-native orchestration, or centralized policy management across dozens of endpoints; Portmaster is single-machine focused and backed by a two-person team in Austria.
